Q3: An apple of mass 0.1kg is thrown at a speed of 100m/s against another apple (mass 0.2 kg, speed 50 m/s), as shown in the figure. After the collision, the bigger apple moves with an upward velocity as shown in the figure. The other apple moves downward at a velocity of 70 m/s and an angle of 27 degrees. a) Write down the equation of conservation of momentum along the x-axis b) Write down the equation of conservation of momentum along the y-axis c) Determine the velocity and the angle of the bigger apple after the collision BEFORE AFTER V= 100 m's =0.1 kg v- 50 m's m2 =02 kg vir- 70 m's
